Aug 21, 2013 5:16 PM in response to CharlieA44by Kappy,★HelpfulOS X v10.6- Gray progress bar appears under Apple logo during startup
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
the Security button and set the Zero Data option to one-pass. Click on
the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

Apr 23, 2014 5:25 PM in response to CharlieA44by robinf40,i have had the same problem with my mac mini. If you go to Macworld and type in, How to split a Fusion drive they will explain how to unlock this drive. Some how when you set up a hard drive it makes it a fusion drive and if you have a ssd in there it block's it out. Try this and let me know how you do >

May 10, 2014 11:42 PM in response to Kappyby khanahmed123,I have MBP late 2011 13"
The issue now is the active disc that contains OS is full with no single byte free and doesn't mount or load OS to computer run and always a grey bar appears upon starting the PC that takes 20 to 30 min
I tried to increase Macintosh HD space from partition but it says you can not change the partition because the disc is locked. When tried to unlock disc from disc utility and than startup disc the PC stands still or hangs up.that means I can't unlock it.
I can not run MBP in safe mode also because the shift doesn't work when trying to open in safe mode.
I don't have Mac OS disc or any apple shop in me area.
Please help me as soon as possible
Thanks indeed
